Where to write these parameters?

Question

tomcat

The Manual has this thing:
Can I change the threshold?

Yes, you can change the threshold and behavior of this alert using the following system properties:

diagnostics.jvm.garbage.collector.percent

diagnostics.jvm.garbage.collector.monitoring.period.secs

diagnostics.jvm.memory.check.period. secs

But it is not written to which file and in what format. in setenv.sh? Then in what format? Through -D -XX: or what?
